From baeacdcfd3ce30b3fa89ebdd4e53c60c38c26c31 Mon Sep 17 00:00:00 2001 From: "Ondrej Zajicek (work)" Date: Mon, 10 Dec 2018 02:11:42 +0100 Subject: [PATCH] OSPF: Fix reconfiguration of vlinks Fix crash during reconfiguration of OSPF config with vlinks. When vlink is reconfigured, a generic iface-reconfiguration code is used, which in one place supposes that it is running on a regular iface. Thanks to Cybertinus for a bugreport. --- proto/ospf/iface.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/proto/ospf/iface.c b/proto/ospf/iface.c index 54a355b6b..388c91c8a 100644 --- a/proto/ospf/iface.c +++ b/proto/ospf/iface.c @@ -531,6 +531,10 @@ add_nbma_node(struct ospf_iface *ifa, struct nbma_node *src, int found) static int ospf_iface_stubby(struct ospf_iface_patt *ip, struct ifa *addr) { + /* vlink cannot be stub */ + if (ip->type == OSPF_IT_VLINK) + return 0; + /* a host address */ if (addr->flags & IA_HOST) return 1; -- 2.39.2
